DESCRIPTION OF THE EMBODIMENTS

Generally, it is not easy to clean the inside of an environmentally friendly straw, and even with a brush, it is impossible to clearly confirm the cleanliness inside the environmentally friendly straw, and it is very easy to derive health problems. In recent years, a part of environmentally friendly straws is designed to be detachable, so that the inside of the straw can be more thoroughly cleaned and the internal cleanliness of the straw can be confirmed. For example, a user needs to stretch his finger into the narrow straw to disassemble the detachable environmentally friendly straw. However, due to structural defect such as a small volume of the straw itself causing insufficient force-applying points, the above-mentioned method does not easily disassemble the straw quickly. The disclosure provides an environmentally friendly straw for easy disassembly to resolve the above problem.

FIG. 1A is a three-dimensional view of an environmentally friendly straw for easy disassembly according to an embodiment of the disclosure. FIG. 1B is an exploded view of the environmentally friendly straw for easy disassembly of FIG. 1A. FIG. 1C is a spread schematic diagram of a bottom of a straw half body of FIG. 1B.

It should be noted that the straw 100A of FIG. 1A only schematically shows relative positions of the components, and is for reference only, and an actual size ratio thereof is not close to that shown in FIG. 1A. Moreover, for simplicity's sake, in FIG. 1C, the bottom of the first straw half body 110 is illustrated in a manner of being spread into a plane, and spreading of the bottom of the second straw half body 120 is similar to the first straw half body 110, which is not repeated.

Referring to FIG. 1A to FIG. 1C, the environmentally friendly straw for easy disassembly 100A includes a first straw half body 110 and a second straw half body 120. The second straw half body 120 is detachably connected to the first straw half body 110 to commonly present a hollow tubular body.

In the embodiment, the top of the first straw half body 110 and the second straw half body 120 is flat. The first straw half body 110 has a first extended part 111 that extends from the bottom of the first straw half body 110. The second straw half body 120 has a second extended part 121 that extends from the bottom of the second straw half body 120.

To be specific, the first extended part 111 is disposed on the bottom of the first straw half body 110 along an extending direction of the first straw half body 110. The second extended part 121 is disposed on the bottom of the second straw half body 120 along an extending direction of the second straw half body 120. The first extended part 111 and the second extended part 121 each have an arc surface part A1.

When an external force is respectively applied to the first extended part 111 and the second extended part 121, the first straw half body 110 may be detached from the second straw half body 120. For example, a user may pinch the first extended part 111 with the thumb and the index finger of his left hand, and pinch the second extended part 121 with the thumb and the index finger of his right hand, and exert a force along an arrow direction of FIG. 1A to separate the first straw half body 110 from the second straw half body 120, as shown in FIG. 1B.

An advantage of such a design is that the first extended part 111 and the second extended part 121 may provide force applying point to user's finger, and the user's finger may be prevented from being confined to a wall of the straw 100A, and may easily and comfortably hold the bottom of the straw 100A. Namely, the first extended part 111 and the second extended part 121 enable the user's finger to hold the bottom of the straw 100A in a larger space to disassemble the first straw half body 110 and the second straw half body 120. In this way, the user may quickly and easily separate the first straw half body 110 and the second straw half body 120 from each other.

In the embodiment, the straw 100A is made of a waterproof and thin material (less than 2 mm), and the material is, for example, a food grade and flexible plastic, but in other embodiments, the material of the straw is, for example, metal, paper, silicone, glass or plastic, for example, stainless steel, polypropylene (PP) or polyethylene (PE). It should be noted that since the straw 100A of the embodiment may be used multiple times, it may mitigate the problems of waste and environmental hazards caused by most of today's disposable plastic straws.

In the embodiment, a manufacturing method of the straw 100A is, for example, injection molding. The first extended part 111 and the first straw half body 110 of the embodiment are integral, and the second extended part 121 and the second straw half body 120 are integral to facilitate manufacturing. But in other embodiments, the manufacturing method of the straw 100A may also be extrusion molding or casting, which is not limited by the disclosure.
